Is Data Sent Via DTS Encrypted?

Jan 27, 2005

Hi all,

I may have a requirement to send data from a SQL Server at site A to an Oracle server at site B. These sites have no network connection between them, and the current suggestion is to use ftp, but the transfer (or username and password) will not be encrypted.

If I create a DTS package transferring data from site A, will that transfer be encrypted?

If not, is there an option with SQL Server DTS to ensure that the data is sent in an encrypted form?

Thanks in advance.

Searching Encrypted Data; Using MAC Secret Data

Aug 10, 2006

I just finished reading an article on how to search encrypted data efficiently and they suggested creating a new column with a Message Auhtentication Code. To be honest, reading the aritcle makes my head hurt. I can hardly understand what they were doing myself and I can't begin to explain it to a developer.

Are there any easier ways to search encrypted columns for a speciifc match? If not, does any have some stored procs that implement this messy MAC stuff?



TIA,

SQL 2005, Replicating Encrypted Data?

Jun 1, 2006

Hello,

I've been searching for information on this for awhile unsuccessully. I am using SQL Server 2005 Enterprise Edititon and transactional replication with separate publisher, distributor and subscribers. I need to encrypt data on our publisher and then I need to replicate that data out (i.e., encrypted data, not encrypted transmission). Since the keys are server specific, I imaging there might be some difficulty in doing this, but I figure I can't be the only one with this problem. Does anyone have a resource or know what must be done to get this accomplished?

Thanks,

Backup And Resore Encrypted Data

Mar 27, 2007

I have two databases, one production and other a production copy.

One column of the production table is encrypted by the following syntax.



CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'password!'



CREATE CERTIFICATE cert_demo

WITH SUBJECT = 'encryption demo'



CREATE SYMMETRIC KEY symkey_demo

WITH ALGORITHM = TRIPLE_DES

ENCRYPTION BY CERTIFICATE cert_demo

-----------------------------------

I have stored procedure to add records to a production table like this.

ALTER Procedure AddRecord

@id int,

@var1 varchar(100)

AS

BEGIN

DECLARE @var2 varbinary(256)

OPEN SYMMETRIC KEY symkey_demo

DECRYPTION BY CERTIFICATE cert_demo

SET @var2 = EncryptByKey(

key_guid( 'symkey_demo' ),

@var1 )

insert into dbo.Test(id,Data,EData)

values(@id,@var1,@var2)

CLOSE SYMMETRIC KEY symkey_demo

END

---------------------------------



Now I need to decript the data in the production copy database. So I had export production data to the production copy database and also generates the same key and cerificate. When i tried to decrypt the data, no results has returned.



Create procedure ViewData

@id int

AS

BEGIN

DECLARE @var1 varbinary(256)

DECLARE @var2 varchar(100)

OPEN SYMMETRIC KEY symkey_demo

DECRYPTION BY CERTIFICATE cert_demo

select @var1=EData from Test where id=@id

Set @var2 = convert( varchar(100), DecryptByKey( @var1))

print @var2

END



It doesn't print the enctypted data. Please suggest what goes wrong.

How To Protect Encrypted Data When DB Is Stolen

Jun 25, 2007

I got a problem concerning encryption. The thing is I have decided to use symmetric key protected by certificate to encrypt certain information. Certificates are protected by database masterkey and by service key.



But I also want to be sure that if someone steals my database with all its data he wont be able to decrypt it with his own SQL Server Management Studio where he has all the permissions.



Also after some time I will need to take my database and set it up on another PC.



Has anyone ideas how to solve this??



P.S. As far as I know if symmetric key is protected by certificate which is protected by DB master key and service master key then you cant decrypt data if database is moved to another workstation and opened with another Management Studio. Please can anyone explain how this works( if its true). And if this is true then how can i move my DB without loosing access to encrypted data???

Searching For Encrypted Fields In Data Columns

Jul 20, 2005

I am new to database programming and was curious how others solve theproblem of storing encrypted in data in db table columns and thensubsequently searching for these records.The particular problem that I am facing is in dealing with (privacy)critical information like credit-card #s and SSNs or business criticalinformation like sales opportunity size or revenue in the database. Therequirement is that this data be stored encrypted (and not in theclear). Just limiting access to tables with this data isn't sufficient.Does any database provide native facilities to store specific columns asencrypted data ? The other option I have is to use something like RC4 toencrypt the data before storing them in the database.However, the subsequent problem is how do I search/sort on these columns? Its not a big deal if I have a few hundred records; I couldpotentially retrieve all the records, decrypt the specific fields andthen do in process searches/sorts. But what happens when I have (say) amillion records - I really don't want to suck in all that data and workon it but instead use the native db search/sort capabilities.Any suggestions and past experiences would be greatly appreciated.much thanks,~s

MAC Used As Search Index For Encrypted Data: How Secure?

Aug 17, 2006

I have read recommendations about searching encrypted data. Typically, they involve creating a MAC (message authentication code) table. One of the elements of that table is a HASH of the encrypted data (plus a Mac key) that is used as an index for searching. Is that HASH as secure as the encrypted data itself, or is this approach less secure? If it is less secure, then may I assume that approach is the only feasible way to search data encrypted by nondeterministic algorithms?



TIA,

Problem Restoring Database With Encrypted Columns To Different Database Or Server With Encrypted Columns.

Jan 23, 2006

I need to start encrypting several fields in a database and have been doing some testing with a test database first. I've run into problems when attempting to restore the database on either the same server (but different database) or to a separate server.

First, here's how i created the symmetric key and encrypted data in the original database:

create master key
encryption by password = 'testAppleA3';

create certificate test
with subject = 'test certificate',
EXPIRY_DATE = '1/1/2010';

create symmetric key sk_Test
with algorithm = triple_des
encryption by certificate test;

open symmetric key sk_Test decryption by certificate test;

insert into employees values (101,'Jane Doe',encryptbykey(key_guid('sk_Test'),'$200000'));
insert into employees values(102,'Bob Jones',encryptbykey(key_guid('sk_Test'),'$500000'));

select * from employees
--delete from employees
select id,name,cast(decryptbykey(salary) as varchar(10)) as salary from employees

close all symmetric keys

Next I backup up this test database and restore it to a new database on a different server (same issue if restore to different database but on same server).

Then if i attempt to open the key in the new database and decrypt:

open symmetric key sk_Test decryption by certificate test;

I get the error: An error occurred during decryption.

Ok, well not unexpected, so reading the forums, i try doing the below first in the new database:

ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY

Then I try opening the key again and get the error again:

An error occurred during decryption.

So then it occurs to me, maybe i need to drop and recreate it so i do

drop symmetric key sk_test

then

create symmetric key sk_Test
with algorithm = triple_des
encryption by certificate test;

and then try to open it.

Same error!

So then i decide, let's drop everything, the master key, the certificate and then symmetric key:

drop symmetric key sk_test
drop certificate test
drop master key

Then recreate the master key:

create master key
encryption by password = 'testAppleA3';

Restore the certificate from a backup i had made to a file:

CREATE CERTIFICATE test
FROM FILE = 'c:storedcertsencryptiontestcert'

Recreate the symmetric key again:

create symmetric key sk_Test
with algorithm = triple_des
encryption by certificate test;

And now open the key only to get the error:

Cannot decrypt or encrypt using the specified certificate, either because it has no private key or because the password provided for the private key is incorrect.

So what am I doing wrong here? In this scenario I would appear to have lost all access to decrypt the data in the database despite restoring from a backup which restored the symmetric key and certificate and i obviously know the password for the master key.

I also tried running the command

ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY

again but this does not resolve the issue.



Thx.

Encrypted Data Size By Original Size, Algorithm ?

Jan 24, 2006

I want to know encrypted data's size for designing database field size.

For example, cardnumber varchar(20) Encrypted by Triple_DES and PassPhrase, How match size does need to encrypted data store field.

I think the size does not depend to PassPhrase char length.

DTSRun Encrypted

Jul 20, 2005

In a Multi Server Job under SQL Server Agent (MSX), we have a series ofsteps like:DTSRun /~Z0x8E8635E6BBA...The ~Z means it's an encrypted hexidecimal string. The person who createdthis step is no longer accessible, and the string can't be triviallydecrypted, so I don't know what this runs.Someone once mentioned that I could go to Query Analyzer, run it, andwatch the execution plan. However, if I start the job, the executionplan simply walks through the steps required to find the job, and doesn'tgo into the details of the job. I don't know how to run the DTSRuncommand directly within Query Analyzer.Is there a way I can use the execution plan to determine what package thisDTSRun line is executing? Please give me the appropriate command orcommands.-Adam

How Are Endpoints Encrypted?

Dec 13, 2007

Hi All,



I have mirroring set up in a test environment and it works great however I need to know/understand how the endpoints are encrypted. I have them set to use the AES algorithm; however I can not tell from BOL what keys they are using. I know the service master key is the root encryption key and endpoints sit at the server level (same level as service masterkey) but I am not sure if the endpoints use it to perform the encryption or not; do they and if not what do they use?



Thanks in advance,



Coleman

Save Encrypted Password

Feb 6, 2003

I have a USERS table on an SQL Server 2000 with two fields, USER_NAME AND PASSWORD, and I want to encrypt the passwords when I stored them on the table.
I used {Encrypt N ‘MyPassWord’} to encrypt the password and it looks that the passwords have been encrypted.

Went, however, I execute a SELECT statement for a specific password all passwords are returned.

This is a small sable code:
------------------------------------------------------------------------------------------------
CREATE TABLE dbo.Users
(
User_Name nvarchar (10) NOT NULL ,
PassWord nvarchar (50) NOT NULL
)

GO

INSERT INTO USERS (User_Name, PassWord)
VALUES ('MyName', {Encrypt N 'MyPassWord'})

GO

INSERT INTO USERS (User_Name, PassWord)
VALUES ('YourName', {Encrypt N 'YourPassWord'})

GO

SELECT * FROM USERS
WHERE PassWord = {Encrypt N 'MyPassWord'}

(2 row(s) affected)
-------------------------------------------------------------------------------------------------
Unfortunately both (All) rows are return

Is it any way to encrypt password and be able to select them?
Is it any other way to encrypt data into the database?

Thank You

Encrypted Stored Procs

Sep 7, 2007

Hey yall

I ran into something interesting today and was wondering how one would do this. I have some 3rd party stored procs and one was kicking out a truncate error so I took it upon myself to investigate the stored proc that was kicking out this error. So when I tried viewing the sp, I received an error:*****Encrypted object is not transferable, and script could not be generated.***** and then it brings up a blank editing screen.

First I believe this was a custom error message as it just doesnt seem like the way SQL Server would have presented it.

So how would someone prohibit viewing of a stored proc like this?

Thanks
